/**
 * <p>
 * A {@link TextView} that insert spaces around its text spans where needed to
 * prevent {@link IndexOutOfBoundsException} in {@link #onMeasure(int, int)} on
 * Jelly Bean.
 * <p>
 * When {@link #onMeasure(int, int)} throws an exception, we try to fix the text
 * by adding spaces around spans, until it works again. We then try removing
 * some of the added spans, to minimize the insertions.
 * <p>
 * The fix is time consuming (a few ms, it depends on the size of your text),
 * but it should only happen once per text change.
 * <p>
 * See http://code.google.com/p/android/issues/detail?id=35466

calling from line 122 with (spanStart - 1), isNotSpace can also return IndexOutOfBounds exception is spanStart = 0. I've changed isNotSpace to return true if 'where < 0'.

I apologize for this but I am still a relative newbie. How do I add this to my app to fix this Nexus issue?

private boolean isNotSpace(CharSequence text, int where) {
if (where < 0 || where >= text.length()) {
return true;
}
return text.charAt(where) != ' ';
}

super.onMeasure() is causing the error in generating signed apk but the code is
working on the emulator. I tried replacing it with super.measure but then code breaks.
Can anybody help me on this ?

Need to fix and simplify isNotSpace() method:

    private boolean isNotSpace(CharSequence text, int where) {
        return where < 0 || where >= text.length() || text.charAt(where) != ' ';
    }
